ABSTRACT
To assess the safety and efficacy of the implantable contact lens [ICL[TM]] to treat myopia. Clinical, retrospective, single center, non-randomized case series. Sixty-nine eyes of 46 patients with myopia ranging from -3.00 to 25.00 D were included in this study. Implantation of the ICL[TM]. Main outcome measures: Uncorrected Visual Acuity [UCVA], refraction, best spectacle corrected visual acuity [BSCVA], adverse events, operative and postoperative complications, subjective assessment and symptoms. The mean follow-up was 12.35 +/- 6.13 [SD] months [range, 6 months-32 months]. At the last visit, 49.20% of eyes had 20/20 or better UCVA compared to preoperative 20/20 or better BSCVA of 31.9% of eyes; 69.23% of eyes had postoperative UCVA better than or equal to preoperative BSCVA. The mean manifest refractive cylinder was 1.93 +/- 1.21 D at baseline and 1.00 +/- 0.92 D postoperatively. The mean manifest refraction spherical equivalent [MRSE] was -11.70 +/- 4.24 D preoperatively and -0.69 +/- 1.13 D postoperatively. A total of 69.8% of eyes were within +/- 0.5 D of the predicted MRSE; 84.1% were within +/- 1.0 D, and 88.90% were within +/- 2.0 D. BSCVA of 20/20 or better was achieved in 64.6% of eyes postoperatively, compared to 31.9% preoperatively. Mean improvement in BSCVA was 1line. One eye [1.5%] lost >/= 2 lines of BSCVA at the last visit, whereas 20% of eyes improved by >/= 2 lines. A total of 56.92% of cases gained >/= 1 line of BSCVA and 4.62% of cases lost >/= 1 line. Four ICL lenses were removed without significant loss of BSCVA, and 2 eyes with clinically significant lens opacities were observed. Four eyes [5.8%] developed a pupillary block the first day postoperatively. One eye [1.4%] developed a hypotony and AC shallowing. Implantation of ICL for the correction of myopia was a safe procedure with good visual and refractive results from the early postoperative period to 1 year. Long-term follow-up is required to confirm the long-term safety of this implant.

Purpose: To present the surgical outcomes of deep anterior lamellar keratoplasty [DALK] for pellucid marginal degeneration [PMD]
Methods: A retrospective review was performed in 16 eyes of 16 patients who underwent DALK at the King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia between January 1, 2006 and December 30, 2009. Baring of Descemet's membrane [DM] during DALK was achieved in 8 [50%] eyes; residual stroma was left intraoperatively in the remaining 8 [50%] eyes. The big bubble technique was performed in 10 [62.5%] eyes and manual dissection was performed in the remaining 6 [37.5%] eyes. Visual acuity [Log-MAR notation], intraocular pressure, intraoperative complications and postoperative graft status were assessed
Results: The mean follow up was 14.6 +/- 8.2 months [range 6-35 months]. The mean overall age was 31.4 +/- 9.6 years [range, 19-50 years]. Visual acuity increased statistically significantly from 0.9 +/- 0.3 [range 0.5-1.6] preoperatively to 0.4 +/- 0.2 [range 0.0-0.7] at last follow-up [p < 0.0001]. There was a statistically significant improvement in postoperative sphere, cylinder, and spherical equivalent [p < 0.035, p < 0.001, and p < 0.02, respectively] compared to preoperative. Postoperative visual acuity was not statistically significantly related to gender, type of surgical technique, and baring or perforation of DM. The main graft-related complication was graft-host vascularization [2/16 eyes]
Conclusion: DALK reduces severe corneal astigmatism and results in good visual and refractive outcomes and is an effective alternative for patients with PMD
ABSTRACT
To assess the outcome of surgical intervention for bleb encapsulation after Ahmed implant. We reviewed the records of 9 patients who developed bleb encapsulation after Ahmed implant and who underwent bleb revision because of uncontrolled glaucoma despite medical treatment. After a mean follow-up of 36 months [range 2 to 84], the mean intraocular pressure [IOP] after bleb revision [16.6 +/- 4.3] was significantly lower than the mean preoperative IOP [28.7 +/- 5.3] [P value <0.05]. Successful outcome was defined as a final IOP between 6 and 22 mmHg with the same or less medication than pre-operatively; this was achieved in seven eyes [77.80%]. Capsular excision after failure of an Ahmed Glaucoma Valve caused by fibrous encapsulation is a useful approach for re-establishing function and lowering the IOP

To report and describe the clinical presentation of malignant glaucoma after Ahmed glaucoma valve implant [AGVI] in 2 patients. Chart review of 2 patients who developed malignant glaucoma after AGVI at the King Khaled Eye Specialist Hospital, Riyadh. Both patients developed high intraocular pressure [IOP] associated with axial shallowing of the anterior chamber despite patent iridotomies and normal posterior segment anatomy following AGVI surgery. Both of them did not respond to medical or laser treatment. However, the anterior chamber deepened and the IOP was controlled in both cases after pars plana vitrectomy and anterior chamber reformation. Malignant glaucoma can develop after AGVI. Successful clinical outcomes can be achieved with posterior segment surgery
